Bitcoin address starting with 3

[Muhammed Zakir]

Its a multisig address. I have one ( look in my profile ) 

 I think about how to get one in my computer wallet ?
Anyone know answer  ? ? ?

You can use any of these to create a multisig address:

 • Bitcoin Core
 • Armory
 • Electrum
 • http://coinb.in
 • https://coinkite.com/
 • http://ms-brainwallet.org/

For tutorials, search in internet and YouTube. It's better to first go to official website of wallets. Most of them publish tutorials on their website.

Not all BTC addresses start with 3, it just means they use different method to generate the private key or something like that.

It might be an invalid address, so dont send bitcoin there until you know what you doing.

Shorena answered it clearly.

Generally address starting with 3 indicate that its a pay to script hash[1] address instead of a pay to pubkey hash address. The script can be almost anything[3] and is not limited to multi signature scripts, its the most commonly used script though.
